Molding apparatus for producing solidified articles

Abstract

A molding system for use in producing a solidified article having a predetermined composite pattern formed of at least two kinds of viscous fluids distinct from each other in color, the system including: at least one discrete passage per each of the viscous fluids, and at least one discrete passage outlet per each of the viscous fluids separately guided through the at least one discrete passage, a method for producing the solidified article, an apparatus for producing the solidified article, and a method for producing the solidified articles.

What is claimed is: 
     
       1. A molding system for use in producing a solidified article having a predetermined composite pattern formed of at least two kinds of viscous fluids distinct from each other in color, said system comprising: a unit mold for molding a single solidified article,   at least one discrete passage per each of said viscous fluids for separately guiding each of the viscous fluids to said unit mold for forming said single solidified article, said each of the viscous fluids having been measured separately to have a predetermined amount,   each of said discrete passages having at least one discrete passage inlet and at least one discrete passage outlet, each of said at least one discrete passage outlet discharging said viscous fluid guided through the discrete passage,   said discrete passage outlets being arranged in a single plane facing the unit mold, and   at least one uniting passage in communication with said discrete passage outlets discharging at least two kinds of the viscous fluids among all of said discrete passage outlets to unite the viscous fluids discharged therefrom,   said at least one uniting passage having a plate having at least one orifice therein for passing the viscous fluids, said plate being disposed in the middle of the uniting passage in a plane transverse to a flow direction of the viscous fluids through the uniting passage,   said at least one uniting passage having at least one uniting passage outlet provided at one end of said at least one uniting passage, said at least one uniting passage outlet facing said unit mold,   said unit mold receiving said viscous fluids discharged through said outlets to mold a single solidified article.   
     
     
       2. The molding system as claimed in claim 1 wherein said discrete passage outlets are arranged in said plane so that at least one of said discrete passage outlets is surrounded by rest of the discrete passage outlets. 
     
     
       3. The molding system as claimed in claim 2 wherein said at least one discrete passage outlet surrounded by said discrete passage outlets is not in communication with any of said at least one uniting passage. 
     
     
       4. The molding system as claimed in claim 1 wherein said unit mold is disposed substantially below said discrete passage outlets. 
     
     
       5. The molding system as claimed in claim 1 wherein said discrete passage outlets are arranged on a single plane substantially vertically facing the unit mold. 
     
     
       6. The molding system as claimed in claim 1 wherein said system comprises a plurality of discrete passages per each of said viscous fluids for separately guiding each of said viscous fluids to said unit mold. 
     
     
       7. The molding system as claimed in claim 1 wherein at least one of said discrete passages has a plurality of discrete passage outlets discharging the viscous fluid guided through the discrete passage. 
     
     
       8. The molding system is claimed in claim 1 wherein said uniting passage has a plurality of uniting passage outlets.
